Bogsveigir should be buffed

the last nerf of this unit made them too weak, Bogsveigir provide very little compared to the other Hill fort units. Theoretically they should excel against myth units, but their base damage is so low, that you need a mass of them and an eternity to kill a tankier myth unit.

There is also the problem that they are only trainable in the hill fort, where you usually want to spam rams and depending on the situation huscarls / jarls.

My suggestion would be to revert those nerfs, or make them trainable in the longhouse in the heroic age. An idea would also be an upgrade that gives them bonus damage against infantry units.
